To all whom, it may concern:

Be it known that I, WILLIAM LOUDEN, a

citizen of the United States, residin at Fairowing is a specification.

This invention relates to carriers adapted to run on a wire cable or asimilar track; and it consists of an improvement in the stop devicetherefor whereby it may be securely connected to the cable and at thesame time be adapted to engage and operate thelock mechanism of thecarrier, as will be described in this specification and more particularlpointed out in the claims.

In the accompanying drawings, which form a part of this specification,Figure 1 is a side view of a carrier embodying my invention, the frameof the carrier on the front side being removed to show the interiorparts. Fig. 2 is a side view of the stop device, the front sides thereofbeing removed to show the interior parts and the wire cable being shownby dotted lines. Fig. 3 is a horizontal section on the line 3 3 of Fig.1, the cable being shown by dotted lines. Fig. 4 is an enlargedtransverse verticalsection on the line 4 4 of Fig. 1. Fig. 5 is ahorizontal section through the locking parts on line 5 5 in Fig. 1, saidparts being shown in full.

Similar letters represent similar parts throughout the several figures.

Referrin to the drawings, A represents one side 0 the carrier-frame, inwhich the track-wheels B B and a rope-wheel or sheave C are mounted inthe usual manner. A rope D is secured to the carrier-frame and is passedover the sheave C in the usual manner, an elevating-pulley E beingpreferably hung in the loop of the rope D.

F and G represent the two parts of a clamp which is applied to the wirecable H by means of boltsI I. In order to make this clamp adhere firmlyto the cable H, I form a projection J in the groove of the part G whereit fits on the cable H and a corresponding recess K in the groove of thepart F. By this means when the parts F and G are firmly clamped upon thecable H it will be bent or kinked between them, so that the clamp cannotreadily slip upon the cable.

L and M represent the main parts of the stop device. These parts aremade in two corresponding halves, preferably a little longer than thecarrier-frame and adapted to hang substantially below the cable Hpartially embrace it between them. At the rear ends they are fitted withcorresponding curved parts N, which are adapted to en-- circle the cableH and to be held in engagement therewith, a bolt 0 preferably being usedto clamp these ends together.

The pieces F and G are provided with ex.- tensions at the ends adjoiningthe parts L and M, and these extensions are fitted with flanges P, whichwhen fitted together make an annular lip. The ends of the parts L and Madjoining the extensions of the clamppieces F and G are fitted withsemicircular grooves Q, which are adapted to fit loosely over theflanges P and to swivel freely thereon. These ends of the pieces L and Mare held together and in en agement with the flanges on the parts F andG by means of the bolt R.

The pieces L and M are each provided with a downwardly-projecting spuror lug S, which coincide with each other so as to form a single lug ordownwardly-projecting prong. The carrier is provided with a dog T,pivoted in the carrier-frame at U and having two upwardly-projectingspurs or prongs V and W on its opposite ends, which are adapted to coactwith the lug S. The free end of the do T is supported by resting on theupper en of a pivoted grappling-hook X. When the pulley E is broughtinto contact with the hook, it is turned on its pivot, so that the freeend of the dog T will drop so the spur V will pass below the lug S, whenthe carrier will be free to run along the cable H.

The carrier being returned to the stop, the spur W will come in contactwith the lug S, which will cause the free end of the dog to rise, andthe pulley E being lowered the hook X will turn on its pivot, so as tosupport the dog in position as shown in Fi 1, and by this means thecarrier will be helrIstationary on the cable.

By referring to Fig. 5 it will be seen that the front spur V of the dogT is rounded in cross-section, while the rear spur is broadened and madeconcave. To accommodate a dog of this construction, the rear faces ofthe spurs S are rounded to approximately and to I correspond with theconcaved face of the spur W, while their front faces are concavedorhollowed out to fit the rounded sides of the The parts L and M arepreferably made concave or recessed on their inner sides, and smallspurs Y are formed on one of them to catch in the recess of the oppositepart and hold them from slipping on each other. The weight of thecarrier and the load it is carrying will at all times be directly uponthe cable, or substantially so, instead of being directly upon the stopieces, as it would be if a sleeve was use or the curved parts N wererun the entire length of the pieces L and M. In that case the entireweight of v the carrier and its load would be upon the pieces L and orbend them unless they were made quite strong and heavy.

j The rear wheel standing upon the short curved parts N will not tend tobend or strain the pieces L and M, and the cable will be free toaccommodate itself to the strain of the load. The swiveled connectionbetween the parts F and G and L and M should be loosely joined, andthere should be sufficient room between the cable and the pieces L and Mso that the cable .will be free to spring or bend at all pointstoaccommodate the strain of the load.

What I claim is 1. In hay-carriers, a clamp adapted to be applied to ahay-carrier track and having an extension on one end thereof, swivelingmeans on said extension and a stop device loosely fitted to the trackand adapted at one end to embrace the swivel end of the clamp and toturn thereon.
